Its intended operating pressure is 6 to 7 bar; it is factory-set to 6 bar. Its noise level is comparable to that of a running desk fan.<\/p>\n<p>The hw wisperflex is designed for reverse osmosis units producing 100 to 700 litres per day at a permeate-to-concentrate ratio of 1:3.5. Increase the operating pressure to a maximum of 8 bar only within the permitted pressure limits of all connected components and in accordance with the equipment instructions.<\/p>\n<p>A fine filter rated at a maximum of 10 \u00b5m must be installed upstream. The pump is intended exclusively for water of drinking-water quality. <strong>It is not suitable for heavily contaminated wastewater or service water.<\/strong><\/p>\n<p>The illustration may differ from the actual product.<\/p>\n<h4>Scope of delivery<\/h4>\n<ul>\n<li>hw wisperflex with 3 m of pressure hose and fitted hose connectors<\/li>\n<li>2 m power cable with earthed plug<\/li>\n<\/ul>\n<h4>Technical data<\/h4>\n<ul>\n<li>Supply voltage: 220 V, 50 Hz<\/li>\n<li>Power consumption: 100 watts<\/li>\n<li>Ingress protection: IP54<\/li>\n<li>Pump delivery: 3600 l\/24 h<\/li>\n<li>Maximum pressure: 8\u20139 bar<\/li>\n<\/ul>\n<p>Smooth-running booster pump for reverse osmosis units producing up to 700 litres per day at a permeate-to-concentrate ratio of up to 1:3.5.<\/p>\n<p><a href=\"https:\/\/hw-wiegandt.de\/en\/aquarium-hardware\/reverse-osmosis-hardware\/\">View hw reverse osmosis equipment<\/a><\/p>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>Use the hw wisperflex to increase inlet pressure for a suitable reverse osmosis system.
